Abstract

Laminated or wound magnetic core made of soft magnetic materials has ferromagnetic adjusting piece inserted in continuous air gap for adjustment of inductance. The air gap (3) can be partly bridged by means of a ferromagnetic screw (7) which is capable of adjustment in the magnetic core. Alternatively the screw (7) is made of soft magnetic material or the material has magnetic properties different from the core (1, 2). The E-core consists of two laminated cores (1, 2). The centre section of the cores (1, 2) is slightly ground, so that an air gap (3) is produced in the centre section when the two cores (1, 2) are pressed together.
